Report Created: September 2024
Two collocated QuantAQ MODULAIR-PM air quality monitoring sensors were installed at a monitoring site in East Hartford, Connecticut to evaluate its performance tracking particulate and meteorology data over a year long time frame. Hourly data for PM2.5, PM10, temperature and relative humidity were compared to reference monitors located at the same site. The full downloadable dataset used is located here Download CSV.
